Application filed June 18,

, the belt is adjusted to the wearer, the retention pad will always be so maintained at the hernial opening that extrusion will be made practically impossible.

The principles of my invention are illus- 15 trated in the drawings in which Fig. 1 rep-- resents a perspective view of my improved apparatus substantially as applied to the body of the wearer; Fig. 2 is a rear view thereof;

Fig. 3 represents the structure shown in Fig.

2 1 when open for application to the figure;

Fig. 4 is a central longitudinal section of the front portion of the apparatus, as indicated on line 44 of Fig. 1; Fig. 5 is a cross-section of Fig. 4 on the dotted line 55; Fig. 6 rep- 25 resents a stay-piece and hasp by which the pad is applied; and Fig. 7 is a rear View of a hernial pad which is adapted to be used with my device.

Further describing my invention with ref- 39 erence to the drawings in which like characters of reference denote like parts throughout: Numeral 1 represents one portion of a belt, preferably of non-elastic webbing; while 1 represents the other portion of the same belt, being preferably made of elastic fabric, which portions taken together are of sufficient length to encircle the body of the wearer. Theyare also of such width and substantial fabric as to provide a stable foundation for the elements tobe attached thereto and which are hereinafter described.

The primary adjustment for length should be made in connection with a back pad 4 having loops 5, 6 and 7 through which the belt members 1 and 1 may be passed so as to lie smoothly on the pad and be adjusted to length by means of the buckle 8. The free end of the portion of the belt indicated by numeral 1 should be encased in a leather casing having the walls 10 and 11 to which it is secured by stitching '12.

The self-adjusting stay-piece is shownin Fig.6. It consists of' an elongated metal foundation plate having a body portion 15 ahead portion 16 and a flange'portion 17 against which is adapted to rest the free edge of the leathercasing sewed to theportion 1 of the belt. A portion 18 may be cut away from the body portion 15 intermediate the endsthereof and rolled to form an eye 19. Hinged to the eye 19 by'means of a pintle22, or in any other suitable manner, is a hasp 20 having a pair of spaced: ears at one end thereof and which are adapted to receive be- 1 tween them thee'ye '19." The major portion of the hasp 20 may be curved as shown in Figs 3 "and 4 to provide an inner concave face .of slight curvature fora purpose to be hereinafter described. The outer and free end of {the hasp'is'relati'vely broad and is provided with an outwardly facing groove or depressionforming a looped hook 23. The body portion-.15 of the foundation plate is provided with a longitudinal slot 24 through which isadapted-to pass a rivet or any other suitable means for securing said plate to said belt, said plate being further secured in said leather casing by means of the stitching 12.

thereof, or in any other suitable manner.

The head portion 16 ofthe' stay piece is provided with atra-nsverse slot '28 through which isextended an a'djustment'bolt 29 having a slotted head 30 and a flange 31 therebelow, which is adapted to seat on the face efthe head 16.. Atruss pad 32 of any desired form has an internal head 33 within which, upon the inner face 34'thereof,is rigidly secured .an elongated guideway 34 having slidablymounted therein a nut'35 which is'threaded to receive the end of the adjustment bolt 29. It will beobserved that, in attaching the hernial padato the inner side of the belt below the stiffening head forming a portion thereof, any desired portion'of the said pad may be brought into any-desired relation with the belt itself; and, when in such position, the application tothe patient-should be made. A suitable-piece of rubber 37 having a longitudinal opening should be placedover the adjustment bolt 29, as shown in the drawing, and it is further noted that for further adjustment, a pin 38 is provided on the head portion 16 uppn which the rubber block 37 may be adjusta 1y 5 placed, as indicated by the dotted lines at 3 thus allowing for ressure to be applied to various, points ofrthe pad; .The elastic portion oflthe truss 1T is provided withva link'39 and a loop 40, adapted to be engaged by the loolpled hook 23 on the free end oi the hasp 29.

a plying the device, the her'nial' pad should placed in approximately operative position with one hand,,while the relatively elastic section 1' is drawn around the body with the other hand bringing the loop 40 under pull of the elastic webbing into engagement with the looped hook 23 onthe en in this operativepzposition, it will be noted that the hasp bears directly on the adjustment screw 29 or 38 as the case may be, which results in a thrust on the pad at right angles-thereto, thus avoiding at all times the possibility of the hernia pad being displaced or moved out, of the hernial opening. Eflrtherdt will be noted that by providing a inner face for hasp, not only is a larger bearing surface obtained between the: has and the resilient means, but also a diioet't rust is assured even when the belt is notjfiat. against the body of the wearer.

1 1:: A'surgical truss comprising a body band, a hernia pad, a stay-plate secured to one end of Said band, means mounted on. and extending. through and in transversely adjustable relation to said stay-plate and connected with said pad, for adjustably securing the pad in position upon the inside of the stay-plate, a

asp-hinged to said stay-plate and adaptedv to bear against said securing means,*for pressing said stay plate and pad inward with respectto' the bodysband, and means for con- 11 the-free end of said hasp with the opposite end of the body band.

2. Asurgical truss comprising a body band, a stayplate secured to one end of said band, ahernia pad, pad-securing means mounted on anidfextending through and in adjustable relation to said stay-plate,lmeans for connectngsaid securing means in. transversely ad- ]ustablerelation to the said pad, pressure applymg means mounted on the outside of and iii-hinged relation to-said stay-plate and adapted to bear against said adjustable padsecuring means, and tending to press said staye plate pad inwardwith respect to the band, and means for connectin the free'en "of said "hinged pressure-app yin meansfwith the other end'of said bod ban I 3. *jfisnrgical "truss comprising a body band provided with fastening means on one" end thereof, a sta plate segured'to the other end of said""ban and 'profided witha transversely-elongated opening therein, a' hernia pad, a securing pin extending throu h said opening and in transversely adjusta le engagement with said stay-plate, for adjustably securing said pad upon the inner side of said stay-plate, means for connecting said securing pin in adjustable engagement with said pad, means hinged to said stay-plate and adapted to bear against said adjustable padsecuring means at one point and against said stay-plate at another point on said hinged means, for applying pressure to said stayplate and pad respectively at different points concurrently, to cause the pad to be pressed inward, and means for connecting the free end of said hinged member with said firstmentioned fastening means.

In witness whereof, I have hereunto set my hand at Chicago, Illinois, this 11th day of June, 1927.
